Jeremiah 25:30

Jeremiah was also to announce that God would prepare to judge all the inhabitants of the earth (Jeremiah 25:29). As a lion announces its intent to attack with a roar, so Yahweh would one day announce His attack on earth-dwellers (cf. Revelation 6). [Note: A less likely interpretation, I think, is that the roar is thunder, the metaphorical voice of God.] He would vigorously tread the nations in the winepress of His wrath (cf. Revelation 14:18-20; Revelation 16:14-16). This anticipates the Tribulation judgments (Revelation 6-18).
